[Abstract]  Cellular infection with tick-borne flaviviruses (TBFVs) results in activation of the interferon (IFN) signaling pathway and subsequent upregulation of numerous genes termed IFN stimulated genes (ISGs) (Schoggins et al., 2011). Many ISGs function to prevent virus pathogenesis by acting in a broad or specific manner through protein-protein interactions (Duggal and Emerman, 2012). The potency of the IFN signaling response determines the outcome of TBFV infection (Best, 2017; Carletti et al., 2017). Interestingly, data from our lab show that TBFV replication is significantly ... [摘要]  蜱传黄热病病毒(TBFV)的细胞感染导致干扰素(IFN)信号传导途径的激活和随后称为IFN刺激基因(ISG)(Schoggins等人,2011)的众多基因的上调。许多ISG通过蛋白质 - 蛋白质相互作用以广泛或特定的方式起作用来防止病毒发病(Duggal和Emerman,2012)。 IFN信号反应的效力决定了TBFV感染的结果(Best,2016; Carletti等人,2017)。有趣的是,我们实验室的数据显示TBFV复制在储库物种Peromyscus leucopus的细胞中显着受到限制,从而表明有效的抗病毒应答(Izuogu等人,2017)。我们评估干扰素信号对抗性的相对贡献。通过敲低IFN反应途径中的主要转录因子来抑制白血病。信号转导和转录激活因子1(STAT1)是专门针对在P。 leucopus细胞通过shRNA技术。我们进一步测试了基因敲低对细胞对IFN反应和限制病毒复制的能力的影响;结果表明当STAT1表达被改变时,leucopus细胞对IFN刺激的反应降低,并且对TBFV复制显着更敏感。

【背景】IFN信号是抵抗侵入宿主细胞的黄病毒的第一道防线(Robertson等人,2009; Lazear和Diamond,2015)。通过模式识别受体(PRR)检测与病毒颗粒相关的分子标记,然后通过转录因子引发下游信号从细胞释放1型IFN(Kawai ...

[Abstract]  Competitive bone marrow transplantation assay measures multi-lineage reconstitution of hematopoiesis in irradiated transplant recipient mice. Thus this assay is routinely used to determine haematopoietic stem and progenitor cells (HSPCs) functionality in vivo. The principle of the method is to transplant bone marrow donor cells (derived from transgenic mice of choice) on C57BL6 background together with normal competitor bone marrow. In order to distinguish donor from competitor cells upon transplantation, usually competitor mice are congenic and carry the differential B cell antigen ... [摘要]  竞争性骨髓移植测定测量照射的移植受体小鼠中造血的多谱系重建。 因此,该测定常规用于在体内确定造血干细胞和祖细胞(HSPC)功能。 该方法的原理是将骨髓供体细胞(源自选择的转基因小鼠)与正常竞争剂骨髓一起移植到C57BL6背景上。 为了在移植时区分供体和竞争者细胞,通常竞争性小鼠是同基因的并携带最初称为Ly5.1和CD45.1的差别B细胞抗原。典型的竞争性骨髓移植实验将含有两个移植组, 供体(选择的转基因小鼠及其对照)与正常竞争剂竞争移植,并在血液和骨髓中评价移入效率。
